Dirham 'Duck type' - anepigraphic Bulghar mint

The "duck type" designation refers to a group of anepigraphic Jochid dirhams whose attribution to Bulgar has been debated — the absence of any mint name or ruler inscription makes precise assignment difficult, and scholars have shifted these coins between attributions more than once. Sagdeeva's classification places this type within a late 13th to early 14th century horizon, a period when the Golden Horde's western mints were producing considerable variety in fractional and subsidiary coinage, some of it deliberately uninscribed for reasons that remain unclear.
